3 wuewtoao J aqa ward coil of relay 1, conductors 22,.and

' 23', and thence to terminal 19. Current in this circuit energizes theforward coils of bess'ed back ioicontectfll. This the followingemrcuit: supply'muin20, relay thetongue b of relay B an tongue 10, contnctlil, tongue of relay 1, which is now over against its forwurdoontact '5, tongue of relay A, which is now a ainst its forward contact a, forward coil 0 relay B, forward :oil of relay 2, whifih sends its tongue to its forward contact 3, conductors 22 and 23, supply main '19. The

tongue .of relay 8 has now made two oscillotions; The first oscillation sent the tongues a and c of relayA a ainst their forward contacts a and a an the second oscillzu tion sent thetongues b and Z1 of relay B against their forward contacts 6 andb.

On the third oscillntipn of the tongue of relay 8, on which it asses over to contact 14, the tongues o an o of relay C will be sent over to their forward contacts a and c,

the tongues of relay A. then returning'to their back contacts. This is brought about by the completion of the following circuit: main 20, to relay tongue 10, contact 14, tongue of relay 2 and its forward contact 3, which said tongue now eng es, thence to its forward contact b, forward coil of relay 0, back coil of relay A, thence through conductors 22 und23 to the supply main 19. This, as above stated, operates relay 0 to send its tongues forward, and the relay A to send its tongues backward.

0n the fourth oscillation of the tongue of relay 8, it passes :1 uin to contact 13 when the forward coil 0% relay D will be energized, sending its tongue forward. At the some time, the back C011 of relay B, which is in series with the forward coil of relay D, will be energized, restoring the tongues of the former relay to their buck stops. 7

In a similar way on the fifth oscilla'ti n of relay tongue 10, the tongues of relay 1 will be sent forward and tongues of the relay C restored to their buck stops, and so on through the series. In this manner the tongues of the relays A to, H are sent suc cessively forward, stay forward until the second relay ahead acts and then return.

On the eighth vibration of relay tongue '10, it will be in mg ement with the contact 13. The relay -1 owever, has not yet received restoring current through its back coil. The tongue of relay 1 is therefore still against contact 5, where it has been since the first oscillation oft-he tongue of relay 10. A circuit from the supply muins ill-20 may then be traced as follows: main.20,'rclay tongue 10, contact 13, tongue of relay 1,

5 its vforward contact 5, relay tongues a, a,

nod of wide uppliootion;

as herein applied to connecting in step-hy- 115 step or successive order, a; series of conducrelay F, restoring the to uesof the letter; completes T-he tongues of all aysA-to H hovenow sent'sucoessively forward, but'oxily the tongues of rehiys'A'to F inclusive have heen restored. A

- On the 'ninth oscillation ofthe inlay tongue-10, 'thetongues of the relay G are restored by the completion of the following circuit: muiu20 relay tongue 10 contact 14, tongue of i'elhy 2 which is still 1 its forward contact 3, since its back coil has? since theccmmenceme'nt of the present cyclereceived no current thence through said con tact 3 to the tongue b of relhy B its back contact, tongue d of relay D and its'back'si; contact, tongue f 'nof relay E and its hack contact, tongue 12. of relay H and its forward contact h, thence through loop 25 tov the buck coil of relay 1, hack coil of relayg, is so through conductors 22, 23 to main 19. restores the tongues of relays G and 1 to their back contacts. i The cycle is completed in the present case with the tenth oscillation of the tongue of relay 10, which brings it a ainst its contact 18, when the-circuit therct rough is as follows: main 20, relay tongue 10 contact 13, to ne of relay 1 and its bac contact 6, bac coil of relay 2,.back coil of relay H, which restores the tongues of these lettertwo relays to their back contacts; conductors 22 and 23 to main 19. All-thg-relayto uesme now restored to the positions with w oh i we started, and if the tongue of relay 8 is kept vibrating, this cycle of Operations may 105,
